Mobile GIS

Mobile GISrefers to an integratedsoftware/hardware frameworkforthe access of geospatial data andservices through mobile devicesviawireline or wireless networks(Tsou,

2004).

(Notebooks , PDA, Tablet PC, Pocket

PC, etc .)

WHY mobile GIS

Field works:data collection and validationprocess, coupled with GPS and wirelesscommunications.

Real-timeupdate / change

GPS integration.


3/36


How GPS and mobile information systems have

enhanced GIS

Ability to define data to be collected prior to

field work

Data dictionaries

Ability to quickly and accurately collectinformation

Location and attribute information

Various levels of positional accuracy

Error checking on attribute entry Compatibility with GIS and CAD systems


4/36


Ways GPS can be used in GIS

Data collection

Recording something, somewhere

What do I have?

What condition is it in?

Data maintenance

Verifying something, somewhere

Is the information I have correct?

Data use Current and accurate data to

support decision making

Finding the asset to perform

maintenance/repair


5/36


GPS/GIS Applications in Planning

Urban & Regional Planning

Data collection/maintenance (rural

addresses, fire hydrant, signpost

inventories)

Cadastral/Land Parcel Delineation

Emergency Planning & Response

Emergency response (wildfire,

hurricane)

Pre-event risk assessment

Forestry

Data collection/maintenance

Tree inventory, logging roads, watershed

Mobile GIS Architecture



Wireless Local Area Network (WLAN)

Wi-Fi or WiMAX Technology

Different from cellular phone communication (CDMA, GPRS)Fast Transmission Speed, Good for GIS applications (large size of data/images)

Wi-Fi-- MIMO (multiple input multiple output). Short distance: 300 feet.

WiMAX(available in late 2006) (Wireless Metropolitan Area Network

(WMAN). 30 75 Mbps, 4 6 miles



Wireless Mobile GIS Integration

Prototype Testing (2003)

(Notebook Web Server (IIS) + ArcPAD + Blue tooth GPS + Wi-Fi )
